gun body 9 and impress the spring member. At that time, a scavenging air valve is opened to fill compressed air into the cylinder body, and thepiston 7 is driven to move in the first direction under the impact of the compressed air in the cylinder body. As the nailing plate 6 is fixedly connected to thepiston 7, the movement of the nailing plate 6 and thepiston 7 is synchronized. Therefore the nailing plate 6 strikes T nails or U nails at the position of the nail outlet 4 into the wood board. - More specifically, the thickness and the nailing plate 6 matches the thickness of the
nail discharge groove 15; Said nailing plate 6 is disposed in thenail discharge groove 15, and is driven to reciprocate therein by the driving unit. In this embodiment, the widths ofnail discharge groove 15 basically cover the specification requirements of various U nails in the market. Therefore, operators needn't to buy different models of nail gun to satisfy different working requirements, thus reducing cost and enhancing universality and facilitation. - It is to be noted that, in this embodiment, a nailing positioning means 20 is provided in the
gun body 9 at the front end of the nailing unit. The nailing positioning means 20 comprises apositioning piece 21, areset shrapnel 22 and afirst guide plate 23, which are sequentially arranged; The tail of thefirst guide plate 23 is socket-connected with aspring member 24; the tail end offirst guide plate 23 contacts thereset shrapnel 22. Thefirst guide plate 23 extends beyond the outer end of thegun body 9, and reciprocates by the coordinated actions of thespring member 24 and thereset shrapnel 22. - In this embodiment, after finishing the procedure of mounting T nails or U nails, the operator can put the
first guide plate 23 of the nail gun against the wood board. As thefirst guide plate 23 is disposed at the front end of the nailing plate 6, the operator should calculate the distance between thefirst guide plate 23 and the nailing plate 6 before nailing, and aim the bottom of the nail gun at the target position of the wood board. Thefirst guide plate 23 firstly contacts the wood board and is in the state ofimpressed spring member 24 and thereset shrapnel 22. When thefirst guide plate 23 is at the same plane as the bottom of the nail gun and the wood board, the operator may actuate the trigger. Now, the nailing plate 6 strikes T nails or U nails at the nail outlet 4 into a wood board. The operator can repeat the process until the nailing work is finished. By the arrangement of nailing positioning means in working process of nail gun, an operator can position the nail gun according to actual needs, thus avoiding nailing mistake, improving working efficiency and significantly reducing manufacturing costs. - The other contents of this example can refer to example 1.
